Laboratory-based DOA tests place considerable distance between the donor and the location of analysis. Anonymity of the donor is essential in the analytical process to remove any potential bias, specimen tampering, result tampering, and breaches in confidentiality. When the collector is also the point-of-collection test operator, there is no anonymity of the donor. This could result in potential abuses of bias, specimen tampering, and result tampering. One method of reducing this potential for error is to separate the functions of the collector from the analytical process, to allow for anonymity in the testing procedure. The POCT technician, who is not the collector of the specimen, would have a separate strand of the chain of custody, without the donor's name or identifying information, similar to the current laboratory model. The ultimate model of local analytical interpretation is to remove the technician altogether, and replace the technician with an instrumented interpretation. Instrumented tests eliminate operator bias and tampering, and preclude result disclosure to the collector and others who are not in a "need-to-know" capacity.
